[GH] John Johnson comments on my last message :
Gordy,
I appreciate the notes on creep. I have one comment. It was my impression that creep is slow rotational movement in the direction of the cast that reduces the available casting arc. Slow horizontal motion in the direction of the cast is not creep it is called drag. Drag is beneficial in that it allows one to assure that the line is straight before it is loaded. It does reduce the available casting stroke.
Am I correct?

[GH] John,
No "right or wrong" here. Depends on how we label these things.
This gets into a "definition" of drag. As you know, we don't have an official one. There has not even been agreement between the various entities coming up with their own lists of fly casting definitions.
Some take the position that linear (translational) movement either before or after the loop has unrolled (or nearly unrolled) is called DRAG. Others have taken the position that it isn't really DRAG unless it is translational movement in the direction of the cast after the loop has (nearly) unrolled.
DRAG,as used by expert distance casters is a bit faster and more energized than CREEP. Some also make the distinction that DRAG is usually purposefully done whereas CREEP usually isn't. Most who attempt to define these things, however, prefer to ignore state of mind (intent). That also speaks to whether or not these moves are to be considered faults or attributes. Having said that, I know most thinkers consider DRAG as advantageous and CREEP as a fault.
High fps video analysis has shown that most of what we call CREEP is rotational... though it may also be combined with some translational movement at the same time.
The whole thing becomes more complicated when we study videos of expert distance casters who use lots of DRAG and note a degree of rotation as they do this !
That puts us in a gray area as to what to call this early translational component... especially when slow rotation and translation occur together. I don't have the answer.
At one point, last year, I came up with my own "working definitions" after deliberating on the discussions during my years on the CBOG Glossary Committee :-
" a.) Drag and Creep are included in the stroke. So is the Casting arc.
b.) I see Drag as tensioning the fly line, starting to overcome inertia of the line, and sometimes taking up slack. Since it is part of the stroke, it neither increases or diminishes the stroke. (It can sometimes delay rotation which has been shown to result in better loop control.) Here, I agree with the SL definition.
3. Drag : Rod translation during the initial part of the casting stroke.
c.) Creep is a faulty portion of the stroke characterized by ineffective force. The wording marginal force is OK with me. I see it as compared with significant or effective force for the remainder of the casting stroke. It's acceleration is minimal ("zero to slow").
Creep is mostly rotational, and so DECREASES THE CASTING ANGLE (CASTING ARC) PORTION OF THE CASTING STROKE. Creep may be combined with some slight degree of translation.
(Years ago, Gary Borger attracted my attention by referring to Creep as a "Two stage stroke". I don't use that term when I teach, but it did make sense.)
4. Creep: Minimally accelerated movement early in the casting stroke which reduces available casting arc.
5. Casting arc : The angular change in the position of the rod during the Casting stroke. "
Others have placed both CREEP and DRAG outside the casting stroke.
Our CBOG committee on definitions (Glossary Committee) never came to full consensus on this despite years of debate.
Since mine are merely "working definitions", I don't claim they are perfect. I'll be happy to change if and when a better set is developed. For now, they work reasonably well for me.
Gordy
